The web has opened a door for new communities and platforms that help people find diverse views and have a voice. Today, anyone with a smartphone can be a content creator, app developer or entrepreneur. And Google has enabled millions of content creators and publishers to be heard, find an audience, earn a living, or even build a business. Much of this is made possible through advertising. Thousands of sites are added every day to our ad network, and more than 400 hours of video are uploaded to YouTube every minute. We have a responsibility to protect this vibrant, creative world—from emerging creators to established publishers—even when we don’t always agree with the views being expressed.

But we also have a responsibility to our advertisers who help these publishers and creators thrive. We have strict policies that define where Google ads should appear, and in the vast majority of cases, our policies and tools work as intended. But at times we don’t get it right.
